One of our forum members, known as “Doublevil,” has made a pretty rad mod for Harvest. It plays more like a standard tower defense game, with upgradeable towers and enemies attacking your base in a straight line. Doublevil has put a lot of effort into it,  you should definitely check it out! You find it here:

Some highlights:

• 17 different towers
• Upgrade menu (with custom-built buttons)
• Nice use of the rush and threat level GUI items
• Some clever particle effects (I first thought it was custom graphics)
• Clean and pretty Lua script, you should definitely take a look

The mod suffers from a crash bug, unfortunately. It occurs sometimes when you upgrade towers, and is likely one of the bugs I’ve fixed for the long lost 1.17 patch… and I still don’t know when we’ll be able to release it…
